SPECIFICATION forming part of Letters Patent No. 409,315, dated August20, 1889.

Application filed January 14, 1889. Serial No. 296,338. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES XV. BURGESS, a citizen of the United States,residing at Norwalk, in the county of Huron and State of Ohio, haveinvented certain new and useful Improvements in Musical Instrumentscalled llarmonicons or Mouth-Organs; andI do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in musical instruments calledharmonica or r 5 mouth-organs, which will be hereinafter moreparticularly described, and pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure1 is a perspcctive view. Fig. 2 is a vertical transverse section on .r xof Fig. 1. Fig. 3 is a top view of Fig. 1. Fig. i is a longitudinaltransverse section on y y of Fig. 1. Fig. 5 is a longitudinal verticalsection of Fig. 1. A is a board of hard wood or block of any suitablematerial, of convenient dimensions for the purpose of a mouth-organ. Inthis board or block A the holes a, I), 0, (Z, and c are bored to suchdepths as to suit the mnsical scale of an octave or more notes. \Vhenthe holes have all been completed, plugs a, b, c, d, and c are then putin the upper ends of the holes, having small openings on one side ofthem, as seen in Figs. 3 and 4, represented in solid black, for the airto pass 3 5 through to the holes below. The mouth-piece B, as shown inFig. 1, is then formed by beveling one corner of the top of A, as at A,and on the opposite side is cuta triangular kert to make an opening ineach hole, 0 so that when the air is blown through the mouth-piece intothe holes the sound of the notes will be produced.

I do not claim a series of graduated pipes, nor a board wherein gradedpipes form a scale.

hat I do claim is A piece of wood having a series of graduated holesbored therein of proper depth and diameter, a triangular-shaped kerf cutlongi- 5o tudinally into'the series of holes to form the lips of thepipes, which pipes have their outer ends filled with flattened plugs,whereby the air blown into them will impinge upon the lips, the upperpart of said board being beveled to form the mouth-piece, allconstructed substantially as and for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES \V. EURGESS.
